Wyoming St., St. Paul, Minn. 55107 FiledJuly 5, 1968, Ser. No. 742,572 Int. Cl. A47f 13/06 US. Cl. 294-19 5Claims ABSTRACT OF THE DISCLOSURE A device for safely switching the highlvoltage terminator on the ends of electrical cables, the deviceincluding a long pole having a working head at one end comprised of apair of movable jaws which can be opened or closed by rotating a handleon the opposite end of the post or pole.

This invention relates generally to fuse pullers.

It is generally well known to those skilled in the art that undergroundresidential distribution systems consist of a group of transformerslocated within vaults in the ground, the transformers being fed by highvoltage primary cables with special terminators on the ends of thecables for connection to the transformers. These terminators are made byRTE and ESNA companies and can be made to be switched on and oif.

A principal object of the present invention is to provide a device whichmay be used for switching on and off the high voltage undergrounddistribution systems.

Another object of the present invention is to provide an undergroundresidential distribution disconnect pole and high voltage fuse pullerwhich includes a long pole of variable length to suit and wherein thereis a working head at one end of the pole which is adaptable tocommunicate with the terminator, and the opposite end of the pole havinga rotatable handle for operating the working head.

Another object of the present invention is to provide an undergroundresidential distribution disconnect pole and high voltage fuse pullerwherein the working head on one end of the pole comprises a pair of jawsfor clamping therebetween the terminator at the end of the electriccable.

Other objects of the present invention are to provide an undergroundresidential distribution disconnect pole and high voltage fuse pullerwhich is simple in design, inexpensive to manufacture, rugged inconstruction, easy to use and efiicient in operation.

These and other objects will be readily evident upon a study of thefollowing specification and the accompanying drawing wherein:

FIG. 1 is a perspective view of the present invention shown partly incross section so to illustrate the interior structure; and

FIG. 2 is a fragmentary side elevation view thereof.

Referring now to the drawing in detail, the reference numeral representsan underground residential distribution disconnect pole and high voltagefuse puller according to the present invention wherein there is a long,tubular pole 11 which may vary in length possible from four to ten feet,the pole having a central longitudinal extending handle 12 therethrough,the handle extending out of one end of the pole where it may be coveredwith a rubber hand grip.

A working head 13 at the opposite end of the pole comprises a bracket 14secured by screws 15 to the end of the pole, the bracket supporting apair of jaws 16. Each jaw includes one end of a bar 17 being securedPatented Oct. 20, 1970 pivotally free on a pin 18 mounted in the bracket14, the

opposite end of each bar 17 having a semi-circular or semi-cylindricaljaw member 19 secured by a single bolt 20.

Intermediate the opposite ends of each bar 17, one end of a pair oflinks 21 are secured pivotally free by means of bolt 22, the oppositeend of the links 21 being secured pivotally free by means of bolt 23 toa block 24 having a threaded opening 25 threadingly engaged upon athreaded shank 26 rigidly secured to one end of the handle 12. The stud26 is fitted within a bushing 27 fitted into a sleeve 28 rigidly affixedto the end of the handle 12, the stud 26 receiving a rivet 29therethrough which extends through the bushing and sleeve.

In operative use, the workman may thus be positioned some distance awayfrom the hot cables and by turning the extending handle which protrudesfrom one end of the pole, he may manipulate the jaws so to close uponthe special terminator on the end of the cable connected to thetransformer. To use the device as a high voltage fuse puller, theworkman can rotate the jaws and install or remove large fuses safely. Itwill be noted that each jaw member 19 also includes a semi-circularnotch 30 along one side edge 31 thereof.

While various changes may be made in the detailed construction, it isunderstood that such changes will be within the spirit and scope of thepresent invention as is defined by the appended claims.

I claim:

1. A tool for electrically insulatably gripping the high voltageelectrical cable terminator of the type having a body portion and a legportion angularly projecting from said body portion, said toolcomprising a longitudinally extending pole, a working head at one end ofsaid pole, said working head comprising a pair of opposing jaw members,said jaw members defining a frontal opening for gripping the bodyportion of said terminator and a lateral opening for gripping the legportion of said terminator, and means for moving said jaw members towardand away from each other whereby said terminator can be gripped andreleased, said jaw members being arcuate shaped, and said frontal andsaid lateral openings being generally circularly shaped, said lateralopening being defined by semi-circular notches in lateral opposing edgesof said jaw members.

2. The tool of claim 1 wherein said pole is tubular, and said meanscomprises: a handle member longitudinally extending through said pole;retractable means connected to the end of said handle adjacent saidworking head; said retractable means being operable from the other endof said handle; and linking means linking said jaws to said retractablemeans whereby said jaws can be moved toward and away from each otherupon advancement and retraction of said retractable means.

3. The tool of claim 2 wherein said retractable means is threaded.

4. The tool of claim 2 wherein said retractable means is operable byrotatable movement of said handle from an axially aligned position.

5. A working head for a tool adapted for electrically insulatablygripping the high voltage electrical cable terminator of the type havinga body portion and a leg portion angularly projecting from said bodyportion, said working head comprising a longitudinally extending pole, aworking head at one end of said pole, said working head comprising apair of opposing jaw members, said jaw members defining a frontalopening for gripping the body portion of said terminator and a lateralopening for gripping the leg portion of said terminator, and means formoving said jaw members toward and away from each other whereby saidterminator can be gripped and 3 released, said jaw members being arcuateshaped, and said frontal and said lateral openings being generallycircularly shaped, said lateral opening being defined by semi-circularnotches in lateral opposing edges of said jaw members.
